Which pairing is correct?

Which pairing is correct?

• A. Calcium Channel Blocker — Amlodipine
• B. ACE inhibitor — Amlodipine
• C. ARB — Metoprolol
• D. Beta blocker — Quinapril

Answer: (A)

Calcium channel blockers relax blood vessels by blocking calcium entry into the muscle cells of the heart and arteries, which lowers blood pressure and reduces chest pain risk. Amlodipine is a classic example of this drug class, so pairing a calcium channel blocker with Amlodipine is correct. Quinapril is an ACE inhibitor, not a calcium channel blocker, and Metoprolol is a beta blocker, not an ACE inhibitor or ARB. ARBs include drugs like losartan or valsartan, not Metoprolol. So the other pairings mix the drug class with a drug that belongs to a different class.
